Thanks for your help. Thanks to yours suggestions I solved my current problem. I've something like this: 1. A main page template that get the values and call a Python Script 2. A Python Script that query a database (calling another script). Then I have the result of the query in a variable. Then my script call another page template to do the rendering of the result. 3. A page template to render the results of the query (so I need to pass the variable with the result of the query). All yours suggestion worked, but I needed to include a line in my script before calling the final page template: contest.REQUEST.set('value',query_result) ... and then everything worked. I'm not sure this is the right way to do it, I'm just starting with zope, Any other comments?

I need to do something like this

<tr tal:repeat="row python:range(value)">

But value come from another template with a form. I always have the same error:

Error Type: TALESError Error Value: exceptions.NameError on global name 'value' is not defined in '', at line 14, column 5

I don't know how to solve this. I want to iterate over a sequence produced by a python script, but I can't pass an argument to the script that came from a form in another page.

Thanks for any help Cristian

Assuming that value is part of the request namespace you could do something like: <tr tal:define="value reques/value" tal:repeat="row python:range(value)">

Minor typo there: that's <tr tal:define="value request/value" tal:repeat="row python:range(value)"> ^ or you can do it all at once, as <tr tal:repeat="row python: range(request.value)"> or, to *make sure* that the value comes from the form variables passed by your last script (as opposed to coming from some other place in the request variable): <tr tal:repeat="row python: range(request.form['value'])">
